Title: Damper apparatus
IPC: F16F9/00
Filed: 1976-06-25
Abstract: Compact damper apparatus for controlling the opposite runs of an endless driving chain passing about a sprocket wheel comprises a pair of oppositely movable spring influenced plungers working in hydraulic fluid filled cylinder bores intercommunicating through a restricted passage. To compact the apparatus, and yet allow it to be mounted with the plungers in an inclined position, the springs are housed in part within the plungers and a single air bleed hole is provided at the highest level inside the hollow interior spring housing part of the uppermost plunger, opening into the plunger/cylinder bore clearance. The proper positioning of this hole allows trapped air which otherwise adversely affects the damping characteristics, to be forced out along the clearance when the apparatus is initially operated, and yet prevents any air being sucked back into the system. An hydraulic fluid reservoir communicates with one of the cylinder bores through a non-return ball valve to ensure that the hydraulic system of the apparatus always remains fully charged.

Title: Malfunction-detecting equipment for real-time supervision of central-office circuits in telecommunication system
IPC: H04Q3/54
Filed: 1978-10-20
Abstract: Sensors SE and actuators AT electrically linked to groups of circuit components to be monitored, e.g. in a central office of a telephone system, are connected to a preprocessor, interfacing them with a microprocessor, which detects an incoming request signal from any group and, after evaluation, sends it on to the microprocessor, causing the latter to emit a confirmation signal which the preprocessor transmits to the corrsponding group actuator. A component-identification signal received from that group and evaluated by the preprocessor is then forwarded to the microprocessor which thereupon, through the preprocessor, instructs the corresponding component actuator to send out an enabling signal to the component thus identified. A response by that component, in the form of an error signal, also undergoes evaluation in the preprocessor and is then passed on to the microprocessor where it is classified and read out to a printer.

Title: Receiving and ejecting a tape- recorder cassette in two steps
IPC: G11B15/675
Filed: 1979-08-04
Abstract: When a cassette is fully inserted in the recorder actuation of the push-key actuator 72 actuates anti-clockwise movement of ejection lever 20c to push the cassette C past the tooth 84 of the braking lever 80 which is biassed against the edge of the cassette by spring 93. Ejection of cassette C is braked by its engagement with the tooth 83 so that complete ejection of the cassette C is prevented, only a small portion of the cassette extending out of the housing. Complete ejection of the cassette C is achieved by pushing it slightly inwardly, the motion causing bistable pin 94 to snap into its alternative stable position which frees lever 20 to continue to rotate under the bias of spring 90 and thus eject the cassette.
